Use and function

The manifold plate is a complex component with a distinct elastic deformation ability for the generation of blank holder, scraper and ejector forces in the tool during sheet metal bending, cutting, forging and forming processes.

The infl uence of a compressive force causes a reversible deforming, which is most distinct for systems that realise energy preservation through the compression of gases. The manifold plate system from STEINEL, as an enclosed component, is based exactly on this mode of action.

A manifold plate consists of the following components:01. Metal plate with volume boreholes02. Pressure cylinder 03. Control panel(s)04. Plug

The metal plate, which acts as a nitrogen buffer, contains bore-holes for the fi xture of pressure cylinders. The manifold is fi lled with nitrogen just like the pressure cylinders, which share the nitrogen reservoir within the manifold plate.

The pressure cylinders consist of the cylinder housing, a piston rod and various sealing and guide units. When the piston rod is pushed in through an external force component, e.g. a press ram, the rod displaces the gas contained in the cylinder housing, which reduces the existing gas volume of the system. The reaction force acting through the piston rod increases proportionally to the declining gas volume.

The positioning of the pressure cylinder depends on the applica-tion and where the piston force is supposed to be made available. A control panel enables the control of the system pressure. It is connected directly to the manifold plate through tubing. In this way, the manifold plate system can be fi lled and emptied in the tool and its readings can be taken there.

To provide for operational safety, burst protections are integrated into the control panel which prevent an unacceptable pressure increase. The system can be set as required by the part (material thickness, tensile strength, yield limit) that is to be produced. These settings can optionally be monitored with electrical or electronic pressure switches.

Advantages

The manifold plate especially stands out because of the small pressure and force increase across the entire stroke range. That makes this system ideal for processes that require con-stant force. Ideally, the initial force only deviates from the end force by a factor of 1.1. This means that the force progression is almost constant throughout the entire stroke curve. In con-trast, system springs, elastomer springs or disc springs have an enormously large force increase during compression.

Manifold plate systems are robust and deliver constant force for an even production quality.

Manifold plates level out forces that are applied unevenly.

In comparison to helical compression springs, manifold plates have greater forces and take up less space.

Compared to nitrogen cylinders (up to 60 %), manifold plates (max. 20 %) have a smaller force increase factor.

The smaller pressure increase within the system results in lower operating temperatures: This increases the life time of the system.

The forces can be adjusted easily through pressure changes at the control panel.

The control panel provides maximum operational safety through integrated burst protection, release valve and a ma-nometer for visual pressure control.

Complex tubing is generally unnecessary. The number of the required screw joint fi ttings is minimised and the system is much simpler and quicker than other solutions.

The reduced number of connecting points that need to be sealed increases the process reliability of the tool.

Buffer system

Should the volume of the nitrogen tank of a manifold plate not be suffi cient, it is possible to connect an external storage buffer. For this you require: Manifold plate External storage buffer Connecting pieces High pressure tube Control panel

The external buffer is connected with high pressure tubes through boreholes in the manifold plate. The pressure can be set and controlled with the control panel: The pressure on all compo-nents within the system is the same everywhere.

Operating medium

Solely technical nitrogen may be used as operating medium. Nitrogen is a neutral, non-hazardous gas.

Filling pressure and cyclic load

A manifold plate is a piece of pressure equipment than can be used for cyclic load. That means that manifold plates can be operated under highly fl uctuating operating pressure. The fi lling pressure can vary between 40 and 150 bar. A manifold plate is designed to limit the pressure increase to a maximum of 20 %. The maximum pressure within a manifold plate is therefore limited to 180 bar and secured via burst protection. The effective application fi eld is displayed on an identifi cation plate.

Because of the fl uctuating operating pressure, manifold plates are subject to cyclic load. That is why the used parts are not critical in terms of fatigue.

The fl uctuation in pressure between the minimum and maximum operating pressure is referred to as load cycle. The difference be-tween the minimum and maximum operating pressure is referred to as pressure fl uctuation range.

Pressure increase

Retraction of the pressure cylinders leads to a pressure increase. There is an appropriate pressure increase for each application. The pressure increase is defi ned as a percentage and can be calculated easily.

p1 x V1 = p2 x V2

Note:

The pressure increase should generally be as low as possible and ideally be 10 %.Please note that a pressure increase that is too high has a nega-tive effect on the life time.We will be happy to assist you with the calculation.

Design

When it comes to the manifold plate design, nitrogen can be con-sidered an ideal gas. Based on this assumption, the behaviour of the gas fi lling in the manifold plate can be described as follows: The state of a gas is determined by the three state parameters

pressure, volume and temperature. Changes to two or all of the state parameters are referred to

as change in state. An isothermal change in state of gases occurs when the

change of the gas buffers in the buffer takes place so slowly that there is enough time for heat exchange and the tempera-ture remains constant as a result.

An adiabatic change in state of gases occurs when the change of the gas buffers in the buffer takes place rapidly and the temperature does not remain constant.

For determining the required manifold plate volume an isothermal change of state can be assumed for purposes of simplifi cation:

p0 x V0 = p1 x V1 = p2 x V2

Selection of the correct manifold plate

Initial questions:

1. How much entire force is needed?2. How many pressure points should this force act on?3. Which working stroke is required?4. What are the maximum dimensions of the manifold plate?5. Which additional milled cavities, boreholes or breakthroughs have to be integrated into the manifold plate?

Design of the manifold plate:

The displaced gas volume during one working stroke of the man-ifold cylinder is calculated by multiplying the piston active surface with the actual stroke and the number of manifold cylinders.

2861.375 cm³Lb = =180 cm = 1800 mm 15.904 cm²

A borehole length of 1800 mm must be used for the manifold plate 700 x 500 x 80 mm, meaning that boreholes with Ø 45 mm require sealing plugs of the type ST 8842-048. These have an installation length of 20 mm. With a plate length of 700 mm and a through-hole, a storage length of 700 - 20 - 20 = 660 mm is achieved. With a total length of the volume hole of 1800 mm, 1800/660 = 2.7 through holes are required. This is rounded up to 3 through-holes. This reduces the pressure increase from 10 % to 9.1 % and therefore has a positive infl uence on the life time of the pressure cylinder.

The end forces are a maximum of 20 % higher, depending on the pressure increase and/or the available volume.

a) Required fi lling pressure

The required fi lling pressure is calculated as follows: Filling pressure = Requested force ÷ Piston active surfacee.g. 400 daN ÷ 4.90625 cm² = 81.528662 bar ~ 81. 5 bar These examples are based on one cylinder each of the type ST 8841-1-005, ST 8841-2-005 or ST 8841-3-005

The required fi lling pressure is calculated as follows: Filling pressure = Requested force x Piston active surface e.g. 6000 daN ÷ 94.98 cm² = 63.171194 bar ~ 63.0 barThese examples are based on one cylinder each of the type ST 8841-1-100, ST 8841-2-100 or ST 8841-3-100


The initial force is calculated by multiplying the piston active surface (94.98 cm²) with the fi lling pressure.Initial force = Piston active surface x Filling pressure e.g. 94.98 cm² x 120 bar = 11397.6 daN
